| titleOfInvention | Manganese dioxide composite nitrogen-sulfur double-doped porous carbon and preparation method and application thereof |
| abstract | The invention discloses a preparation method of manganese dioxide composite nitrogen-sulfur double-doped porous carbon. Dissolving thiourea in a dilute acid solution to prepare an acidified thiourea solution, dripping the acidified thiourea solution into a mixed solution in which sodium alginate, potassium nitrate and potassium permanganate are dissolved, and crosslinking to obtain the massive gel. And after washing and freeze drying, carrying out one-step carbonization at a certain temperature under the protection of nitrogen to obtain the manganese dioxide composite nitrogen-sulfur double-doped porous carbon. The method utilizes acidified thiourea and a sodium alginate molecular chain to crosslink to obtain gel, wherein the thiourea can be used as a nitrogen source and a sulfur source at the same time, and the potassium permanganate is used as a manganese source, so that the manganese dioxide composite nitrogen-sulfur double-doped porous carbon can be prepared by one-step carbonization. By changing the concentration of potassium permanganate, the regulation and control of the pore structure and the manganese dioxide content of the porous carbon can be realized, and the supercapacitor taking the porous carbon composite material as an electrode material shows good electrochemical performance. |
